Application April 17, 1950, Serial No. 156,274

1 Cl m- 1 This invention relates to improvements in sweepers.

I An object of this invention is to collect dust, dirt and the like by means of an improved device which brushes the dirt rearwardly on a tray which is disposed between side panels, the side panels supporting a motor which drivingly operates the brush at the front of the device.

Another object of this invention is to provide an improved device of the nature to be described which is commercially feasible from a production standpoint and which operates satisfactorily.

Other objects and features will become apparent in following the description of the illustrated form of the invention.

In the drawings:

Figur 1 is a plan view of the device, parts being broken away in section to illustrate internal detail;

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1 and in the direction of the arrows;

Figure 3 is a rear view of the device in Figure 1;

Figure 4 is a longitudinal sectional view taken substantially along the line 3-4 of Figure l and in the direction of the arrows; and,

Figure 5 is a perspective view shown exploded, of some of the elements forming the case of the device.

In carrying out the invention I have provided a handle H! which is bifurcated at its lower end, the bifurcations l2 and I4 terminating in eyes which are disposed on the trunnions l6 and I8. These trunnions are fixed to the side panels l9 and 20 which are generally triangular in shape, with two corners rounded. The handle is used for the expected purposes of pushing the devices from place to place. In forward locomotion of the sweeper the brush 24 which is mounted on the shaft 26, assists.

A tray 30 which includes a flat bottom 32 and vertical sides 3-3 and 35 rising therefrom, is disposed on the flanges 38 and 45 which project laterally from the lower edge of the side panels l5 and 20 respectively. There is a back 42 of the tray which rises above a recessed portion 44 at the junction of the back 42 and the bottom 32. This recessed portion form an external passageway for the tray rod 46 which passes through openings 41 and M3 of the side panels I 9 and 26 in order to assist in retaining them assembled. Appropriate fastening media such as a head on the tray rod and a nut at the other end is employed to hold said tray rod in proper disposition.

A platform 50 having depending flanges at each end, is fixed as by bolts 5! above the tray and to the inside surfaces of the side panels 19 and 20. This platform accommodates the conventional motor 52 which has a driven pulley 54 at the end of its power shaft. A belt 56 or other driving elements such as a chain, is entrained around the pulley (in using a chain, a sprocket will be employed at this point) and around a pulley 58 which is fixed to the shaft 26. Accordingly, in operation of the motor 52, as by use of a conventional switch, the pulley 58 actuates the shaft 26, thereby actuating the brush 24 for urging dust, dirt and other objects rearwardly into the tray 3!].

A hood 6!! having its forward end terminating adjacent the brush 24 and above it, is disposed on the upper edge of the side panels l9 and 20, being shaped to conform to the configuration thereof and has its rear part 62 forming a rear panel for the case. Any suitable means may be employed to hold the hood Bl] fixed to the side panels l9 and 26.

A bracket 64 is fixed to the back 42 and has a vertically adjustable screw 66 carried thereby. This vertically adjustable screw has a castor 68 on the lower end thereof whereby by operation of the screw, the castor is raised or lowered. The tray 30, resting on the flanges 38 and 40, is held in place by the :bolts ll having wing nuts thereon (Figure 3) and which extend through openings in the side panels I 9 and 20 as well as in the sides 34 and 36 of the tray. Accordingly, to remove the tray 39, as for emptying it, the bolts H and the rod 46 are removed and the tray slid through the rear of the case.

At the forward end of each side panel l9 and 20 there are wheels 69 and 10. Recesses 12 are appropriately provided in the side panels to accommodatethese wheels and a mounting bracket 14 is employed to hold each wheel shaft in place. The mounting bracket is fixed to the inside surface of each side panel.

A notch 78 is supplied in the tray side 34 and a notch 86 of the same configuration, is supplied in the forward end of the side 36 of the tray, These notches are of such shape as to snugly fit over the rear end of the mounting brackets 14 to assist in retaining the tray 30 assembled with the side panels I 9 and 20. Recesses 82 and 84 are provided in the side edges of the bottom 32 of the tray in order to provide the necessary clearance for operation of the wheels 69 and I0. I

In order to further assist in retaining the sides 19 and 2B in fixed relationship with respect to each other, the stay rod 90 which passes through openings in the front of each side panel is used.

Having described the invention, what is claimed as new is:

A sweeper comprising a casing open at its front, bottom and rear, said casing including a pair of side walls and a forwardly and downwardly inclined top, inturned flanges on the lower, rear portions of said side walls, supporting wheels on the forward portion of the casing, mounting brackets for said wheels on the side walls, a rearbottom, a back and side walls, said side walls of said tray having notches therein for the reception of the brackets for supporting the front of said tray in the casing, means for releasably securing the tray against sliding movement on r the flanges, said means comprisin a removable '1 rod extending between the housing'side walls, the

N r r.

tray having a recess in its rear, lower portion accommodating said rod, a brush rotatably mounted in the casing forwardly of the tray, 9. platform mounted in the rear of the casing above the tray, a motor mounted on said platform, and means operatively connecting the motor to the brush for sweeping matter into the tray.
